Operating and Safety
Instructions
Warning: Static Electricity
Static sparks can cause explosion resulting in
severe injury or death.
Ground the pump and the pump connections
like hoses and containers into which or from
the uid is being transferred. Connect the
grounding wire to any bolt on the pump.
Check continuity of electrical path to ground
at regular intervals.
Consult local building and electrical codes for
grounding requirements where needed.
Use hoses containing a grounding wire.
Warning: Pump Exhaust
In case of a diaphragm failure, u-
id being pumped may spray out from the
exhaust of the pump. is may cause severe
injury depending on the uid being pumped.
If the uid is hazardous, pipe away the
exhaust to a safe remote location using a
generous diameter pipe preferably with a
grounding arrangement, and ret the muer
at the end of this arrangement.
Always wear safety glasses while in the
vicinity of an operating pump.
Warning: Over pressure / Hazardous Pressure
Do not exceed the max supply air pressure of
100 PSI.
Make sure all connected hoses and pipelines
are rated to operate safely with the pressures
generated by pump of 100 PSI.
Do not open or handle pump or hoses while
pressurized.
Disconnect air supply line and relieve
pressure from the system by carefully opening
discharge and supply lines.
Warning: Hazardous Materials
Do not move a pump that contains
hazardous uids trapped inside it. Please
observe prescribed handling and safety codes.
Drain the pump safely, by turning it upside
down and collecting the uid safely, before
moving the pump.
Warning :Explosion
Please check compatibility of uids
intended to be handled with the materials of
construction of the pump. Severe reactions
and explosions may occur if materials are
incompatible. Caution: Chemical
compatibility

FF-MM-302-REV - 00
Page 4
Operation and Maintenance Guide DPB40 Plastic Pump Series
Please check that the uid being pumped is
compatible with the wetted parts of the pump.
Refer Cole Parmer compatibility (http://www.
coleparmer.in/Chemical-Resistance) guide
for details. Note that chemical compatibility
may change with temperature; take this into
account while selecting pump material.
Caution: Structural support
Please refer gure 1 and ensure that the
piping system is independently supported
and does not load the pump. e pumps are
not designed to take the continuous and oen
pulsating load of a piping system. Important
to use a exible connection between rigid
piping and pump casings.
Caution: Running dry, disconnection of hoses when
not in use
Although these pumps can be run dry for
long periods, it is advisable to avoid this as it
causes unnecessary wear of wearing parts.
Caution: Operator
understanding
Please ensure that all operators have read this
manual and have the required understanding
of safe working practices and are equipped
with safety equipment when working on/
around the pump.
Caution: Using genuine

Use genuine teryair parts to ensure correct
pump operation and maximize life.
 
e Teryair diaphragm pump generates a alternate stroking of the diaphragms against the
uid in the liquid chambers of the Pump. is reciprocatory action is responsible for the uid
being pumped.
It is possible to control the output of the pump by controlling the supply air pressure.
It is also possible to control the output of the pump by throttling action on the uid owing
in the outlet piping by means of a valve. if such a valve is shut completely the pressure in the
discharge piping increases to a point when the pressure at pump discharge equals it and the
pump comes to a stop. is causes no damage to the pump and the pump consumes no more
energy.
Upon opening of the valve, the pump starts reciprocating once again and resumes uid deliv-
ery.

Operation and Maintenance Guide DPB40 Plastic Pump Series
Location selection
Pump location must be easily accessible with reasonable
space around for maintenance operations.
Pump dimensional data for each variant is available in
section showing exploded views
Air supply
Compressed air at 90 PSI ( Stroke pumps can take a max
of 100 PSI), free from moisture and having an oil mist is
essential. Use of a lter (50 microns), a lubricator and a
regulator is highly recommended and should be installed
as close as possible to the pump inlet.
Ensure correct grade of oil is used in thelubricator bowl.
Too thick oil may slow down the valve shiing mecha-
nism and aect pump performance. See suggested lubri-
cants on page no 5.
Piping
A minimum number of bends and ttings to be used.
A exible connection between suction, delivery and air
supply piping is highly recommended such that piping
stresses and loads do not transfer to pump housing.
Select piping materials such that chemical compatibility is
maintained with the uid being pumped.
Suction
Ensure that the suction head aer installation is well
within the pumps suction capabilities

Use of supplied muer is recommended to bring pump
operation sounds down to comfortable levels, in case of
hazardous uids handling, please read section of safety
regarding piping away of exhaust see
Warning: Pump Exhaust) earlier in this manual.

Troubleshooting
Serial No Description Causes Remedial Action
1 Pump stops and
will not start
Insucient Air Pressure Check air pressure is as recommended
at the pump air inlet
Air Filter Blocked Check if debris has clogged the inlet l-
ter on the FRL unit/pump inlet air valve
( some models have air lter on the air
inlet valve ) and ensure clear passage of
air
Internal damage or excessive wear
on components
roceed to dismantle the pump, examine
component for wear, replace any worn
components, re assemble carefully as
instructed in this manual and re start
the pump.
2 Pumps runs slowly,
poor delivery
Cavitation Check if cavitation is occurring in the
suction side, if so reduce suction vacu-
um by slowing down the pump.
Worn Balls and Seats Check proper sealing action of balls
against seals, these components need to
be replaced as a set if they are worn.
Insucient or wrong lubricant in
the air supply.
Ensure that the lubricant is as per the
recommended chart, a thicker lubricant
oen makes the air valve work sluggish-
ly
Internal damage or excessive wear
on components
Proceed to dismantle the pump, exam-
ine component for wear, replace any
worn components, re assemble carefully
as instructed in this manual and re start
the pump.
3 Pump air valve
frerzes
Excessive moisture in supply air
line.
Ensure that the dew point of the
supplied air is low enough. Install a
air dryer or moisture separator on the
supply line
4 Air bubbles in
pump discharge or
product sprays out
of exhaust vent
Broken Diaphragm
Proceed to dismantle the pump,
examine component for wear, replace
any worn components, re assembly care-
fully as instructed in this manual and re
start the pump
mproper seal between inner
pistons, outer pistons and sha.
Air leakage into product from
balls / seats area
Air sucked into suction pipeline
due to insuciently tight joints on
suction pipeline.
